BUILDING coNsTnoc'rxoN.

Patented oef.. 1, 1907.

To all 4whrtt'l, may co'llccm: "le't known that I, Lnms K. Davis, a citizenof the United States, and a resident of the cit-y oi New York, in the county ol New Yoik and State oi New York, 5 United States of America, have inventcdcertain new and useful Improvements in Building Construction, of whiehthe following is a specification.

My invention relates to an improvement in systems of building construction and its object is to provide a simple and inexpensive iircproof construction for floors or other structures.

Iwill describe my invent-ion in the following speciiication and point out the novel features thereof in claims. l A l 1 l Referring to the drawings, lFigure l is an end elevation of a tileo -speeialdesign which I have invented.

-Fig. 2 is a side elevation oi the same. Fig. 3 is a sectional elevation of a floor made according to my invention. Fig. 4 is a sectional elevation o f a portion of l .20 a floor showing a ln'mliiication' of my invention.

Like characters ot' reference designate corresponding part-s in all of the figures. flO designates a ltile in the form oi a rectangular trough having a latbody portici 11 and side portions v12, 12 vwhich extend -vert-ic lly from the sides of the'body port-ion 1I. `The 'sides are provided with flaring projections 13. 13. These may be in the form of bossesor may bc, :is shown in the drawings, in the forni of parallel ribs 'extending along the entire length v ofthe tile.-

14, 14 designate strengthening ribs which extend 'downward from the fiat body portion 1l `of thc tile. The depth 'of the tile is added to -thereby so that itsstrength is materially increased without addii'c.;

greatly to its weight. The tile may be constructedl of.

any suitable material such, for example, as vit-riied clay. I prefer 1o have it salt glazed.

In usingtiles of the above described form for the construction oi a. floor a plurality oi them are laid sido 404 by side as 'Shown in Fig. 3 with intervening spaces between the tiles. The tiles :ire preferably laid in 'straightlongitudinal rows and if desired the tiles. in

adjacent rows may be staggered. The bottoms of the intervening spaces between the adjacent rows of tiles may be closed by a. board'or plank 21. The spaces between the tiles niay then beflled with concrete or cement 2O which may be poured into the spaces in a semi-liquid condition. In conjunction with this concrete iilling I prefer to use metallic reinforcement ,such, for example, as steel rods 22, 22 embedded in theeoncrete. The concrete is allowed to harden after which thebosrd will be removed. It will then form a portion of the structure itseli. The concrete will cling to the sides ofthe tiles, and because of the flaring shape oi the projecting ribs 13, 13', will securely lock 55 and hold the tiles together.- The trough portion of the' tiles may tlicn be .filled with einders or other suitable material u's shown at'23so as to' form a continuous fiatl surface for the floor` In themoditcation illustrated in Fig. 4 I have shown '60 a plank 21A placed under and between adjacent Ytiles but extending from one oi the projecting .strengthening 4ribs 14 on one tile toa similar rib on the adjacent tile.'

In this case the concrete filler will not only completely lill the intervening spaces between the. adjacent tiles but will also extend underda portion of each tile. and thereby increase the strength of the structure. I have also shown in this figure a wooden door of ordinary construction laid on top of the-tiles and their filling material. .-v. 70 Aloor constructed according to this invention has great strength.` Its extreme simplicity and ease oi setting up'gi've advantages te lthis construction not found in other structures of this class, andthe. structure thus formed is light, inexpensive and absolutely iireproof. I have shown this construction as used in forming a floor but it obviously applicable to other structures.

What I claiuiic 1. A floor comprising :i plurality of ln|ilding,tiics scf in pui-:Alici rows with intervening spaces between the rows, euch of said tiles comprising :i tint bod) portion` strengthening .ribs extendingdownwnrd from said body portion. side portions extending vertically from the opposite sides of the body portion and flaring projecting.: ribsupon the cuter surface of said side portions; und concrete between the sides of adjacent tiles, said concrete filling the intervening spaces und locking the i'ilestogethcr.

2. A floor commising a plurality of buildingr tiles set in parallel rows with intervening spaces between the rows. 90

each of said tiles comprising :i flat. body portion,'stren;,fth ming ribs extending downward from said body portion thereby increasing the effective depth of the tile, side portions extendingvertlcnlly from the opposite sides of the body portion and ilaring projecting ribs upon the outer I surface of said side portions; concrete between the sides oi' adjacent tiles, said concrete extending under a portion ot' each of said tiles between the projecting ribs thereof, und metallic reinforcement embedded in saidconerete.

In testimony whereof I have signed my naine to this 10C specification in the presence of two subscribing witnesses.
